Short Circuit Analysis

A short circuit study determines the short circuit currents available at various points in the electrical distribution system. Knowledge of these values is critical in determining the rating of each piece of equipment in a facility’s electrical system.

A protective device coordination study is the evaluation of the system’s overcurrent protective devices, such as relays, fuses and circuit breakers and the circuits they protect. The coordination study compares each device’s operating current levels and the length of time within which each protective device operates, in order to properly operate without system damage or failure. Coordination studies are performed to ensure that the protective device closest to the overload or short circuit condition is the one that operates in order to isolate the failure as quickly as possible.
